CrystalDiskMark 3.0 Tests

Each of our tests with the Crucial m4 SSD were consistent, and the best results obtained were used in the chart below. Sequential tests on this Marvell solid state drive produced a maximum read speed of 410.0 MB/s while the write speed was 277.0 MB/s, compared to 500.6 and 300.5 MB/s for the OCZ Vertex 3.

Based on our tests, it seems that performance emphasis has switched read and write priority when compared to the previous RealSSD C300 series. The new Crucial m4 SSD stands strong all on its own, but it's too soon to tell how well these minor tweaks appeal to consumers. Compared head-to-head, SandForce 2200 SSDs appear to offer better performance than Marvell 88SS9174 revisions, which could make it difficult for the Crucial m4/Micron RealSSD C400, as well as Strontium SSD Matrix, Intel SSD 510, Corsair Performance 3, and others to thrive.

For the Crucial m4 SSD to succeed it must be aggressively priced against the competition, but the five-year warranty certainly sweetens the deal. The complete Crucial m4 Solid State Drive review is goes into more detail on these points. Micron officially launched the Crucial m4 SSD on 26 April 2011, offering the following capacities: 64GB Model $150, 128GB Model $260, 256GB Model $520, 512GB Model $1000.
